Daniele Filippetto
Organisation: Berkeley Lab Role: Staff scientist in the Advanced Light Source Accelerator Physics Division
Daniele Filippetto is currently the lead scientist for HiRES, the High Repetition- rate Electron Scattering apparatus, which is part of Berkeley Lab’s APEX (Advanced Photo-injector EXperiment). Some of his recent work involved
creating algorithms to better control particle beams and lasers using a new machine-learning platform. Filippetto said: ‘We are trying to teach
physics to a chip, while at the same time providing it with the wisdom and experience of a senior scientist operating the machine.
Munjal Gajjar

Role: Vice-president, R&D department
Not everyone in R&D can point to their work having an effect on their nation’s economy, but Munjal Gajjar can. Based in the Indian city of Surat,
which reportedly cuts 90% of the world’s diamonds, Gajjar said the industry was once almost entirely dependent on imported technologies. Costs were higher and delays waiting for replacement parts could halt production, so he and STPL set about creating an indigenous solution. ‘We developed state-of-the-art
technologies for every stage of diamond processing. The solutions based on lasers,

AI and robotics by STPL are now being used in five continents,’ he said. Gajjar said diamonds benefit greatly from laser cutting – 'it is safer, more efficient and less prone to error', vital in an industry whose exports were estimated at $24.2 billion in FY 2021-22. ‘Photonics has the potential to further enhance the accuracy of a diamond-cutting process and thus advance the yield to a great extent,’ he said.

Laura Gemini
Organisation: ALPhANOV Role: Group manager, nanoscale laser processing & health applications
As manufacturers come under increasing pressure to cut waste, Alphanov’s Laura Gemini is clear on how ultrafast lasers can help to deliver. She sees the next big thing as ‘intelligent integrated systems for ultrafast laser-based manufacturing able to adapt in real time to meet mass production throughputs while maintaining the unique advantages of this technical approach, such as a superior writing resolution’. While Gemini believes ultrafast laser
systems will allow resource consumption and waste production to be minimised, challenges remain around cost and throughput before it

can competitively be integrated into high-tech manufacturing lines. ‘To achieve this it will be essential to
achieve fibre transport of high average power ultrafast lasers for manufacturing of complex 3D parts, while keeping all laser beam properties steady and stable to fit industrial needs. The development of robotic positioning systems that can guarantee high movement speed and high positioning precision and repeatability will be imperative.’ You can find Gemini online at

Based in: Berkeley, California, USA Education: PhD in Engineering from the Uni- versità degli Studi di Roma ‘La Sapienza’
He has also recently published research
into the use of ultrafast electron pulses. In June 2022, he was the lead author on a paper that presented a summary of the developments in this field over the past few decades. In that study, Filippetto and his colleagues presented the physics and technology of ultrafast electron beams with an emphasis on the figures of merit most relevant for ultrafast electron diffraction (UED) experiments.
